Definition of pollutionPollution is the introduction of contaminants
into a natural environment that causes instability,disorder,harm or discomfort to the ecosystem .
Pollution can take the form of chemical substances or energy such as noise, heat or light.
Air pollution
What is air pollution Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
CAUSES OF AIR POLLUTION- Industries.-Automobiles and Domestic fuels-High Proportion of undesirable
gases,such as sulphur dioxide and carbon monoxide
EFFECT OF AIR POLLUTIONAir Pollution affects???
Human healthAnimals PlantsThe atmosphere as a whole
How to prevent air pollutionCarpoolWalk or ride a bicycleConnect your outdoor
lights to a timer or use solar lighting.
Wash clothes with warm or cold water instead of hot.
Plant trees etc…….
Water pollution
What is water pollution Water pollution is the
contamination of water bodies. E.g. lakes, rivers, oceans,
groundwater. Water pollution affects plants and organisms
living in these bodies of water; and, in almost all cases the effect is damaging either to
individual species and populations, but also to the
natural biological communities. Water pollution occurs when
pollutants are discharged directly or indirectly into water
bodies without adequate treatment to remove harmful
compounds.
Causes of Water PollutionAbout 40% of Deaths
worldwide are caused by Water Pollution.
Water Pollution is Caused by organsic and inorganic industrial wastes and affluents discharged into rivers.
Effects of Water PollutionDiseases like CholeraMalariaTyphoid (spread during the rainy season )Aquatic life gets destroyed
How to prevent water pollutionRivers should not be
used for washing clothes or bathing animals in.
Dams should be created.
In sacred rivers like Ganga dead bodies shouldn’t be thrown.
Noise pollution
NOISE POLLUTION Noise pollution is
displeasing human, animal or machine-created sound that disrupts the activity or balance of human or animal life. The word noise comes from the Latin word nausea meaning seasickness. The source of most outdoor noise worldwide is transportation systems, including motor vehicle noise, aircraft noise and rail noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area.
Causes of Noise PollutionTraffic NoiseAir craft NoiseNoise from construction
and civil engineering works.
Noise from the Industries.
Noise from other sources.
Effects of Noise PollutionHearing LossHigh Blood PressureStressSleep DisturbanceColor Blindness
How to prevent noise pollutionThe government
should ensure the new machines are noise proof.
Airports should be away from residential areas.
‘No horn’ boards should be put on/near school areas.
We should talk less and work more.
Land pollution
LAND POLLUTION Land pollution is the
degradation of Earth's land surfaces often caused by human activities and their misuse of land resources. It occurs when waste is not disposed properly. Health hazard disposal of urban and industrial wastes, exploitation of minerals, and improper use of soil by inadequate agricultural practices are a few factors. Urbanization and industrialization are major causes of land pollution.

How to prevent land pollution
More and more land should be brought under farming.
Trees should be planted everywhere.
Waste matter should be disposed immediately
Avoid drilling lands for underground water.
Avoid using fertilizer and pesticides for farming.
